WELL-AUG-ER POINT.

Specification of Letters latent.

Application filed April 25, 1911.

Serial No. 623,267.

To all whom it may concern:

Be it known that I, Goti rrm'nn A. ESTEL, citizen of the United States,residing at Jacob, in the county of Jackson and State of Illinois, haveinvented certain new and useful Improvements in Well-Auger Points, ofwhich the following is a specification.

This invention has relation to well auger points, and has for its objectto provide a simple structure which may be quickly and easily operatedor manipulated for the purpose of boring a pump well.

With the above object in view, the structure includes a pipe sectionprovided at its upper end with a hollow T which may be used as a handleor a sleeve through which a bar may be inserted, the said pipe sectionbeing provided at its lower portion with a circumferential rib and alongitudinally disposed spline. A sleeve having a slot .is adapted toslip upon the lower end of the pipe section with the slot receiving thespline, the said sleeve being adapted to abut at its upper edge againstthe said rib. A spirally disposed blade is located upon the outerperiphery of the sleeve and an auger point is inserted in and carried bythe lower end of the pipe section.

F or a full understanding of the invention reference is to be had to thefollowing description and accompanying drawing, in which:

Figure l is a perspective view of the well auger point; and Fig. 2 is asectional View of a portion of the same.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

The well auger point includes a pipe section 1 provided at its upper endwith a hol low T 2 which may be used as a handle or through which a barmay be inserted for the purpose of rotating the section 1 and itsattachments. The section 1 is provided in the vicinity of its lower endwith a peripheral annular rib 8, and the said section is provided uponits outer side below the rib 3 with a longitudinally disposed spline 4.A sleeve 5 is adapted to slip upon the lower end of the section 1 andabut at its upper end against the rib 3. Said sleeve is provided with alongitudinally disposed recess or socket 6 which receives the spline 4.An auger point 7 is inserted in and carried by the lower end of the pipesection 1.

To operate the device the auger point 7 is inserted into the ground andthe pipe sections may be connected with the section 1 by removing thehandle 2 and replacing it on a newly connected pipe section. In this waypump wells can be sunk quickly, with less effort and less broken threadsthan usually attends driving wells. When it becomes necessary towithdraw the pipe section 1, the sleeve 5 with the blade 8 slips offfrom the lower end of the section 1 and remains in the earth. The augerpoint 7, however, being separate from the sleeve 5 and carried by thepipe 1 will withdraw with the said pipe. The only loss in pulling thepipe 1 from the earth is the sleeve 5 and blade 8. In order to preventthe adhesion of the sleeve 5 to the pipe 1 by rust a suitable anti-rustmaterial may be used as a lining.

Having thus described the invention, what is claimed as new is:

1. A well auger point, comprising a pipe having a peripheral rib andprovided with a longitudinally disposed spline, a sleeve adapted toreceive the end of the pipe and abut against the rib, said sleeve havinga slot which receives the spline, a spirally disposed blade carried bythe sleeve, and an auger point carried by the pipe.

2. A well auger point, comprising a pipe having a peripheral rib andprovided with a longitudinally disposed spline located between the riband the end of the pipe, a
